-Device-tree bindings for FSI-attached I2C master and busses
------------------------------------------------------------
-
-Required properties:
- - compatible = "ibm,i2c-fsi";
- - reg = < address size >;		: The FSI CFAM address and address
-					  space size.
- - #address-cells = <1>;		: Number of address cells in child
-					  nodes.
- - #size-cells = <0>;			: Number of size cells in child nodes.
- - child nodes				: Nodes to describe busses off the I2C
-					  master.
-
-Child node required properties:
- - reg = < port number >		: The port number on the I2C master.
-
-Child node optional properties:
- - child nodes				: Nodes to describe devices on the I2C
-					  bus.
-
-Examples:
-
-    i2c@1800 {
-        compatible = "ibm,i2c-fsi";
-        reg = < 0x1800 0x400 >;
-        #address-cells = <1>;
-        #size-cells = <0>;
-
-        i2c-bus@0 {

+  This I2C controller is an FSI CFAM engine, providing access to a number of
+  I2C busses. Therefore this node will always be a child of an FSI CFAM node.
